Playback and Recording 3 Chapter
Notes
•The color temperature display that appears after white balance adjustment is calculated on the basis of the R/G/B signal output from the camera. It may not agree with the results of measurement by commercially available color temperature meters. The camcorder’s color temperature display should be regarded as an approximation.
•If the camera has a zoom lens with an automatic iris, the iris may hunt 1). To prevent this, adjust the iris gain knob (indicated as IG, IS, or S) on the lens.
For details, refer to the lens operation manual.
1)Hunting: Repeated brightening and darkening of the image, resulting from repeated response to automatic iris control.

About the white balance memory
Values stored in memory are held until the white balance is next adjusted.
There are two sets of white balance memories, A and B, which you can switch between with the WHITE BAL switch (PRST/A/B).
On the WHITE SETTING page of the MAINTENANCE menu, when WHT FILTER INH is set to OFF, there are two memories, A and B for each position of the ND filter of this unit (CLEAR, 1/4 ND, 1/16 ND, and 1/64 ND).
In this case, the memory is switched as you change the ND filter position, for a total of eight (4×2) memories.
If a memory error occurs
If the error message “: STORED DATA: NG” flashes on the viewfinder screen when the camcorder is turned on, the white balance memory contents have been lost. Adjust the white balance again. Contact your Sony dealer if this message continues to appear even after the white balance has been adjusted again.
